Description

Copies part of an image from another matrix layer

Copies part of image from another matrix layer It copies only the part of image in source matrix layer that is within grObject

Syntax

BOOL CopyImage( MatrixLayer SrcLayer, int left, int top, int right, int bottom, BOOL bUndo = TRUE )

BOOL CopyImage( MatrixLayer SrcLayer, GraphObject grObject, BOOL bUndo = TRUE )

Parameters

SrcLayer: [input] Source matrix layer
left: [input] Rectangle left position in the source matrix layer to copy image from
top: [input] Rectangle top position in the source matrix layer to copy image from
right: [input] Rectangle right position in the source matrix layer to copy image from
bottom: [input] Rectangle bottom position in the source matrix layer to copy image from
bUndo: [input] Whether to support undo(TRUE) or not (FALSE). default is TRUE

SrcLayer: [input] source matrix layer
grObject: [input] closed graphic object (polygon, rectangle or circle)
bUndo: [input] Whether to support undo(TRUE) or not (FALSE). default is TRUE

Return

TRUE if success; otherwise FALSE
